CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 14/495,518, filed Sep. 24, 2014, now U.S. Pat. No. 9,457,876, which claims the benefit of U.S. Provisional Patent Application Ser. No. 61/882,765, filed Sep. 26, 2013, the disclosure of each of which is incorporated herein by reference as if set out in full.

BACKGROUND

The pool noodle is a flotation device usable in water, typically a pool. While ubiquitous today, the pool noodle has only been a water toy since about the mid 1980s.

With reference to FIG. 1, a conventional (or original) pool noodle 100 is shown. The pool noodle 100 is formed of extruded foam, such as a polyethylene, polypropylene, or polyurethane foam. The extruded foam is cut at an appropriate length for the particular use. The extruded elongated foam element is called a “noodle” because its shape is similar and its flexibility is similar to noodles. In part, due to the extrusion process, the pool noodle 100 has a hollow bore 102 extending through the center of the pool noodle 100. Conventionally, the pool noodle has a diameter 104 of about 2 to 4 inches and a length 106 of between 1 to 7 feet, depending often on the desired use.

The pool noodle 100 is highly buoyant and is often used as a personal flotation device where a swimmer holds the pool noodle 100 and the buoyancy of the pool noodle 100 supports the swimmer. The pool noodle's flexibility allows for alternative uses as well. In some embodiments, the pool noodle 100 may be formed into a square shape (either continuously or cut) to form a floating holder for a cooler of beverages in a body of water. In other instances, a rope may be threaded in the hollow bores 102 over a plurality of pool noodles 100 to a string of pool noodles. In still other instances, a pool noodle 100 may be formed into a shape, such as a U, L, or V shape and used by an individual.

Pool noodles 100 may also be used, in certain applications, as swords or jousting items to allow individuals to safely have a mock battle. In other non-traditional uses, the hollow bore 102 of the pool noodle 100 may be filed with fluid and used as a water gun.

Despite the many and varied uses for pool noodle 100, the pool noodle 100 remains essentially a single piece of extruded foam. Thus, against this background, improved pool noodles are desirous.

 DETAILED DESCRIPTION

The technology of the present application will now be described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the technology of the present application. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense.

The technology of the present application is described with specific reference to pool noodles. However, the technology described herein may be used for other applications outside of pools, such as, for example, use in water parks, other bodies of water, or uses outside of water, and the like. For example, the technology of the present application may be applicable to sledding, or the like. Moreover, the technology of the present application will be described with relation to exemplary embodiments. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. Additionally, unless specifically identified otherwise, all embodiments described herein should be considered exemplary.

With reference now to FIG. 2, a multiple strand pool noodle 200 is shown floating in a pool 10. The multiple strand pool noodle 200 comprises a first end 201 and a second end 202 opposite from the first end 201. The multiple strand pool noodle 200 comprises a first end member 204 at the first end 201 and a second end member 206 at the second end. The multiple strand pool noodle 200 comprises a plurality of strands 208, which in this case, is seven (7) individual strands 208. Each strand 208 is itself an extruded foam member, generally hollow in view of the extrusion process presently used, but solid strands 208 are contemplated by the technology of the present application. The strands 208 each may be a conventional pool noodle, such as the elongate foam member 100 above, having a diameter between about 2 to 4 inches. However, as shown, the multiple strand pool noodle 200 comprises elongate extruded foam members having a diameter D of approximately 1 to 3.5 inches. In certain aspects, the diameter may be between about 1.5 and 1.75 inches. In some embodiments herein, the diameters may be less than 1 inch to 1 inch. As used herein in conjunction with dimensions, approximately and about mean within manufacturing tolerances, and for this type of product may be ±10%. Also, while shown as identically sized and shaped strands, the strands 208 may be of varied sizes and shapes. For example, instead of seven (7) circular cross-section members, the strands may include other cross-sectional shapes including, circular, triangular, rectangular, star, crescent, oval, tear drop, or the like. Generally, however, the length of the strands 208 forming the single multiple strand pool noodle 200 are of about the same length to couple with the ends 204, 206.

The first and second end members 204, 206 in this embodiment are formed of foam similar to the strands 208. In this exemplary embodiment, first and second end members 204, 206 may be formed from extruded foam similar to the strands 208 (or 100 above). In some embodiments, the first and second end members 204, 206 may be formed from a sheet of foam material made in any conventional manner and wrapped about the strands 208. If formed of a sheet of foam material, the seam (not specifically shown) would be heat fused or otherwise adhered to form the first and second end members 204, 206. The seam may be otherwise adhered using glues or other weld technologies that are applicable.

With reference now to FIG. 3, an elevation view and an end view of the multiple strand pool noodle 200 is shown. As can be seen in the end view, the first end portion 204 (and similarly second end portion 206), in this exemplary embodiment, is a tubular member that is open on both ends such that the strands 208 may extend from one or both sides of the first end portion 204, which is useful in one method of constructing the multiple strand pool noodle described further below. In some embodiments, however, the first (and/or second) end portion 204 (206) may include a cover such that the ends of the individual strands are not viewable when the multiple strand pool noodle 200 is constructed. As can be seen from the end view, the strands 208 are symmetrically arranged with six (6) strands side to side about a single center strand. While shown as seven (7) strands, the multiple strand pool noodle 200 having end members with a generally circular first and second end members 204 and 206 could have as little as three (3) strands to an almost unlimited number of strands.

With reference now to FIG. 4, a multiple strand pool noodle 400 is shown. Similar to multiple strand pool noodle 200 above, multiple strand pool noodle 400 has a first end 401 with a first end member 404 and a second end 402 opposite the first end 401 with a second end member 406. The multiple strand pool noodle 400 further has a plurality of strands 408 that, in this exemplary embodiment, include seven (7) strands 408 although the multiple strand pool noodle may contain two (2) or more. As can be seen from the end view, the inner width D2 of the first and second end members 404, 406 is approximately equal to the diameter D1 of the strands 408. Moreover, the inner height H of the first and second end members 404, 406 is approximately equal to the diameter D1 of the strands 408 times the number of strands that are stacked, which in this case is seven (7).

As shown in FIG. 4, the first and second end members 404, 406 are formed by an oblong tubular member that wraps around the top and bottom strands 408T, 408B. Alternatively, as discussed above, the first and second end members 404, 406 may be formed from a single sheet of foam material that is wrapped about the strands 408. In still another embodiment, the first and second end members 404, 406 may be formed from multiple sheets of foam 500 as shown in an elevation view in FIG. 5.

In one exemplary embodiment, manufacturing the multiple strand pool noodle 200 or 400 comprises gathering the determined amount of strands 208 or 408. The strands 208, 408 are placed into the first and second end members 204, 206 or 404, 406 with an excess length of the strands 208 or 408 sticking out the end. The excess length does not need to be uniform for each of the strands 208, 408. For example, as shown in FIG. 6, an end member 600 is shown with four (4) strands 602. The end member 600 has an end surface 604. The strands 602 each extend beyond the end surface 604. The strands are organized such that the lengths are similar (although not necessarily uniform) and sticking out of the end member 600 beyond the end surface 604 by approximately ‘½’ in this exemplary embodiment. More or less of the strand ends may extend from the end member in other embodiments. The end member 600 and strands 602 are heated as a group and allowed to melt together for approximately 2-3 seconds. Subsequent to the melting, cooling may be applied to cure the multiple strand pool noodle. The individual pieces outlined above are now joined to each adjacent edge beside it such that the end member 600 and the strands for an integrated unit with a smooth end surface. Instead of melting the ends to form an integrated or monolithic unit, the strands and end members may be welded, glued, or chemically bonded.

With reference now to FIGS. 7 to 13, the versatility of the multiple strand pool noodle 200 is demonstrated. First, with reference to FIG. 7, the multiple strand pool noodle 200 is usable as a conventional pool noodle. In this use, the swimmer grasps the multiple strand pool noodle 200 as a conventional flotation device. FIG. 8 shows another use of the multiple strand pool noodle 200 that is similar to a conventional use of a conventional flotation device. In this application, the pool noodle is used as a seat in a U-shaped harness. With reference to FIGS. 9 and 10, the multiple strand pool noodle 200 is used in a seat configuration. In particular, the strands are separated to form various seat configurations. For example, in FIG. 9, several of the strands 208 are arranged across the back of the swimmer and several of the strands 208 are arranged across the thigh/buttocks region. The configuration of the multiple strand pool noodle 200, in FIG. 9, provides a floating seat with a back support. Similarly, with reference to FIG. 10, the strands 208 are fanned out in a planar arrangement under the thigh/buttocks region of the swimmer. This configuration provides a stable, generally flat seating surface (similar to a sling or seat hammock) for the swimmer as opposed to the generally round surface shown by the inverted U-shaped harness of FIG. 8. FIGS. 11 and 12 show a lounge configuration for a pool use of the multiple strand pool noodle 200 not possible with a conventional pool noodle 100. With reference to FIG. 11, for example, a first plurality of the strands 208 are fanned out to support the upper back, neck, and head of the swimmer and a second plurality of strands 208 are fanned out to support the legs, shown in the knee region. This allows the swimmer to rest in the supine position on a single multiple strand pool noodle 200. Similarly, FIG. 12 shows the use of the multiple strand pool noodle 200 in another lounge configuration. In this configuration, at least one strand of the strands 208 are used on the left and right side of the supine swimmer as a sort of guard rail. The remainder of the strands 208 are fanned out and extend under the back generally parallel to the spinal column. Finally, the first (or second) end 201 (or 202) and the first end member 204 (or the second end member 206) may be used as a head rest. Finally, in FIG. 13, the multiple strand pool noodle 200 may be used similar to a conventional pool noodle 100 as a means of launching liquid, similar to a squirt gun.
